Ambry Genetics

Feb 13, 2024

The c.464G>A (p.R155H) alteration is located in exon 2 (coding exon 2) of the STARD7 gene. This alteration results from a G to A substitution at nucleotide position 464, causing the arginine (R) at amino acid position 155 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
